Understanding the mechanics of the functional interface Predicate of a Stream is crucial if you want to create something meaningful with streams.

In this challenge, we will explore important key methods when we work with a stream so that it becomes clear for you what they do.

Without further ado, let’s go to the Java Challenge!

Learn how, with a bit of creativity, we were able to utilize off-the-shelf functionality and components to set up lightweight cross-cluster communication for apps in a multitenant environment.

While this solution is applicable to a somewhat narrow use case, it does come with several important advantages, including shared-nothing architecture, low complexity, low operational burden, and high degree of isolation between tenants.

Foojay community members and beyond discuss embedded Java, featuring the following speakers:

James Gosling, creator of Java and embedded enthusiast; Frank Delporte, engineer with Toadi, an autonomous lawn-mowing robot; Johan Vos, founder of Gluon, helping make fully cross-platform applications.

Hosted by Erik Costlow, developer relations for Contrast Security, locating security flaws in backend systems.

Marco Faella’s book “Seriously Good Software” teaches intermediate Java programmers to write better software, using an entirely different approach.

I can warmly recommend this book to Java programmers who have learned to code and strive to code well.

I think it is a particularly rewarding read for computer science students who had several semesters of disjointed knowledge of programming, algorithms, computing systems, and software engineering.

To celebrate OpenJDK 17 and Foojay.io as a community platform for its users, we’re kicking off the Virtual Foojay OpenJDK 17+ JUG Tour.

Ari Waller, JFrog’s Event Manager, well known to many JUGs, will continue to wear a second hat—that of Foojay Event Manager.

During September and October, contributors to Foojay will be making a whistle stop tour through as many JUGs as possible, via their virtual meetups! (And if you’re not holding virtual events or don’t have the facilities for this, we can support by making these available as needed.)
